Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a container-integrated container bag having a variable superstructure,

The present invention relates to a body part integral type container bag. More particularly, the present invention relates to a body part integral type container bag having a variable top structure and a manufacturing method thereof.

Conventionally, the container bag is provided with an independent upper plate separate from the body portion, and attached to the body portion. In this case, since the process of joining the body and the upper plate is added, the process time is long and the process cost is increased. Also, the durability in the case where the bonded portion was broken was also a problem.

Furthermore, a dead space (dead space) that occurs when the contents are filled in the conventional container bag has been a problem. That is, if the contents bag is lifted and flattened by the self-load after the contents are injected into the container bag and the container bag is lifted after the contents are closed, a dead space is generated between the top surface of the contents and the top plate of the container bag. Such a space has a problem of reducing the contents to be transferred.

The present invention has the technical features of the body portion and the superstructure of the container bag. The container bag according to the present invention may be used as it is, or a separate baffle bag may be additionally inserted into the container bag, or a partition wall may be provided at the inner edge thereof.

Hereinafter, the present invention will be described with reference to the drawings. 1 to 3 show an exploded view and a perspective view of a container bag according to an embodiment of the present invention.

The present invention relates to a container bag (10) having a variable top structure formed of a container bag fabric (1) integrally formed with a body part, and includes a body part (100) and an upper part (200), i.e., a top plate.

The body part 100 according to the present invention is a hollow or polygonal columnar hollow body. The cylinder according to the present invention includes not only an ideal cylinder but also a partially deformed cylinder and an elliptical column. In the polygonal column according to the present invention, the corners of each side portion may be clearly divided, but the corners may be rounded. It also includes some deformations in the prismatic shape due to the load of the contents. For reference, the present invention will be described using square columns.

The container bag according to the present invention is connected to the upper side of the second upper region 220 and the upper side of the second upper region 220 so as to reduce the flat cross-sectional area at the upper end of the body portion 100 having a constant cross- (Not shown).

The body 100, the second upper region 220, and the first upper region 210 are all formed by folding and integrally folding the same container bag fabric 1 together.

The first upper region 210 according to the present invention may include a plurality of remainders 223 spaced apart by downward incision and downward refraction (see Figs. 1 to 3).

The second upper region 220 according to the present invention may be provided with a folding portion 222 formed by downward folding and a corner folding engaging portion 230 folded to the left and right sides (refer to FIG. 3).

Hereinafter, various embodiments of the incision 221 formed in the first upper region 210 of the present invention will be described. 9A-9D and 10A-10D illustrate various exemplary embodiments of the first upper region of the present invention and the resulting container bag appearance.

It is preferable that the downward incision in the first upper region 210 is formed not to be in contact with the longitudinal side dividing line 111 of the body portion but to be bilaterally symmetrical. Symmetric shape is realized when mutual coupling is performed later.

The incision improvement according to the present invention can reduce the incidence to the longitudinal side dividing line 111 toward the lower side (see FIG. 9A).

The incision reduction according to the present invention is possible to reduce the distance from the longitudinal side dividing line 111 toward the lower side (see FIG. 9B).

The incision 221 can be an embodiment in which a part is parallel to the longitudinal side dividing line 111 and the other part is closer to or away from the longitudinal side dividing line 111 as it goes downward. Here, the upper and lower relationships between 'part' and 'part' can be changed with each other. A possible embodiment is as follows.

The incline reduction according to the present invention may be such that an upper portion thereof is parallel to the longitudinal side dividing line 111 and a lower side portion is closer to the longitudinal side portion dividing line 111 as the lower portion is lower.

The upper part of the incline according to the present invention can be distanced from the longitudinal side dividing line 111 as the upper side portion is parallel to the longitudinal side dividing line 111 and the lower side portion becomes lower side as shown in FIG.

The incline reduction according to the present invention can be made such that a lower portion thereof is parallel to the longitudinal side dividing line 111 and an upper side portion is closer to the longitudinal side dividing line 111 as it goes downward (refer to FIG. 10A).

The incline reduction according to the present invention can be made such that the lower part thereof is parallel to the longitudinal side dividing line 111 and the upper side part is away from the longitudinal side dividing line 111 as the lower part is lower.

It is also possible that the incision 221 is partly closer to the longitudinal side dividing line 111 and the other is farther from the longitudinal side dividing line 111 toward the lower side. Here, the upper and lower relationships between 'part' and 'part' can be changed with each other. A possible embodiment is as follows.

The upper part of the incision according to the present invention can be moved away from the vertical side dividing line 111 as the lower side is lowered toward the longitudinal side dividing line 111 and the lower side is lowered as shown in FIG.

The incline according to the present invention can be made such that the upper part is away from the longitudinal side dividing line 111 and the lower side is closer to the longitudinal side dividing line 111 as the lower side goes down.

Meanwhile, in the above-described various embodiments, if the shape of the opening 225 is suitable for loading the contents, the opening 225 may be treated as the first inlet 224. However, for example, in the case of the embodiment of Fig. 9A, an embodiment may be adopted in which a separate second inlet 226 communicating with the opening 225 is additionally provided.

Two embodiments of the folding of the folding portion according to the present invention are also possible.

The folding part 222 according to the present invention can be folded inward of the body part. In this case, the folding portion 222 is not exposed to the outside of the body portion (see FIGS. 4C and 4D).

Further, the folding part 222 according to the present invention can be folded outside the body part. In this case, the folding portion 222 is exposed to the outside of the body portion (see Figs. 5C and 5D). The present embodiment can prevent the contents and the friction of the folding portion during transportation from abrading the folding portion into the contents. Therefore, depending on the kind of the contents accommodated in the container bag, it is possible to appropriately select folding downward or downward folding of the folding portion.

In both of the above embodiments, when the folding portion is folded downward and folded back to the left and right, the corresponding portion becomes a total of four folds, so that there is an advantage that the rigidity to withstand the load applied to the corner is secured.

Hereinafter, the binding of the lifting ring 300 according to the present invention will be described. Fig. 11 and Figs. 12A to 12D show engagement positions of the lifting hooks according to the present invention.

The contact point X1 between the corner folding joining portion 230 of the first upper region 220 and the first upper region 210 and the contact X1 between the body portion 110 and the second upper region 220 X2) (see Fig. 11).

The height H2 connecting the contacts X1 and the height H3 which is the boundary between the body 110 and the second upper region 220 can be distinguished from the upper and lower viewpoints (see FIG. 11).

The space between the vertical line of the contact point X1 and the vertical line of the contact point X1 and the vertical line of the contact point X2 can be divided into the B region (see FIG. 11).

In the case of the A region, the lifting ring 300 may be engaged in at least one of the body portion 110 and the second upper region 220. However, it is not preferable to be coupled to the first upper region 210 (see Figs. 12A to 12C).

In the case of region B, it is preferred that the lifting ring 300 is not coupled to either the body 110 or the second upper region 220. In the case of the B region, the lifting ring 300 is preferably coupled to the edge folding engagement portion 230 (see FIG. 12D). The lifting hooks 300 may be inserted into the folded portions of the edge folding coupling portions 230 and may be coupled to the outer edges of the edge folding coupling portions 230.

Since the container bag according to the present invention is provided with a lower plate, the lower plate 400 may further be coupled to the lower end of the body 100. A discharge port (not shown) may be formed in the lower plate 400. However, when the charging and discharging are also performed in the openings 225 to 224 of the upper plate or the upper structure, the lower plate may have no discharge port.

Hereinafter, the conventional container bag and the container bag according to the present invention will be compared in terms of dead space (dead space).

13A and 13B show that dead space is generated when contents are accommodated in the conventional container bag.

When the contents are injected into the conventional container bag as much as possible, the contents will reach up to the height h1 from the inside of the container bag, as shown in Fig. 13A. Since the contents are fed into the container bag and have a constant inclination, the contents will reach down to the height h3 of Fig. 13A. That is, as shown in FIG. 13A, the dead space 120 has already occurred at the time of implantation.

As shown in FIG. 13A, when the inside of the container bag is filled to such an extent that no more contents can be injected, the inlet is sealed. It is then lifted up for movement. When the container bag is lifted, the content is partially lowered by the load of the charged contents, and the upper surface of the contents is flattened at a height h2 between the height h1 and the height h3 as shown in FIG. 13B. 13B, it can be seen that the final dead space 120 is generated. Because the gravity acts, the contents will be moved down by the weight of the contents, so that the dead space in Fig. 13B will generally be larger than the dead space in Fig. 13A.

The height from the bottom to the top of the actual container bag is h1. Considering this height, the number of container bags to be loaded on the container, the mass of the contents to be transported, and the like are calculated. However, in the case of the conventional container bag, the contents can not be filled up by the volume according to the self-contained value of the container bag. This is a very inefficient transfer from the point of view of conveyance of the container bag.

Hereinafter, a description will be made of a process of filling contents in a container bag having a variable superstructure according to the present invention.

9C, a variable superstructure according to the present invention will be described. 14A, 14B, 15A and 15B show that in the container bag according to the present invention, the dead space is minimized by using the variable superstructure.

The container bag according to the present invention has a structure in which the second upper region 220 has a flat cross-sectional area smaller than that of the body portion 110. Sectional area is smaller than the body part due to the corner folding part 230 formed by folding the folded folding part 222 downward and folded back to the left and right.

First, the embodiment of Fig. 14B will be described. 14B corresponds to the embodiment in which the height H2 of the second upper region 220 is maintained and the height of the top plate of the container bag is H2.

Also, according to the present embodiment, the first upper region 210 also has a constant inclination. Therefore, it is possible to have a slope similar to the slope generated when the contents are injected into the container bag. That is, as shown in FIG. 14A, the generation of the dead space 120 is minimized in the process of injecting the contents. When the contents are injected, the maximum height of the contents can be H1. When the injection of the contents is completed in this manner, the inlet is closed. It is then lifted up for transport.

 When the container bag is lifted, the contents are partially lowered by the load of the charged contents, and the upper surface of the contents can be flattened uniformly at a height H2 as shown in FIG. 14B. When injected in this way, the height of the present container bag can be calculated as the height H2. And the height H2, the number of loads, the weight of the load, and the like will be calculated.

Here, the height H2 means the height of the second upper region 220, which actually increases or decreases by a certain height.

Next, the embodiment of Fig. 15B will be described. The embodiment of FIG. 15B corresponds to the embodiment in which the height H2 of the second upper region 220 is not maintained and the height of the top plate of the container bag is H3.

This may be the case where the content injected less than the height H1 or the contents which are not pressed down by the self-weight of the contents during lifting (see FIG. 15A). Also, even if the height H1 is injected, it may correspond to a case where the degree of pressing down by the self-lifting load is considerably large.

15A may correspond to the case of the former. As shown in FIG. 15A, after the injection port is closed and lifted for transporting, it is assumed that the final height of the contents becomes a height H3 as shown in FIG. 15B. Here, the height H3 means the height of the body portion 110, which actually increases or decreases the height of the body portion 110, and includes the increase or decrease of the height.

As described above, the container bag according to the present invention has an advantage that the actual height of the container bag can be made variable by using the variable top structure. It also has the advantage of minimizing dead space.
